When growing in windy environments, this organism will grow low along the ground, but when growing in sheltered environments, it grows tall. the leaves have a waxy coating to reduce moisture loss, a chemical makeup that makes them fairly fire resistant, and produce a scent that deters predators. it also has a large root system and root crowns. what organism and environment is described above? a. coyote brush and chaparral b. cacti and desert c. mesquite and savanna d. coyote brush and taiga?

Over the past 60 years, many amphibian species have experienced significant population declines and some species have become extinct. scientists suspected that local human activities such as the destruction of wetlands, regional pollution, and deforestation were the main reasons for these losses. however, research over the past 20 years reveals significant amphibian population declines in protected areas of the world, such as nature preserves and parks. these global declines suggest widespread problems including increased ultraviolet radiation, acid rain, and disease. in switzerland, for example, 14 of the 20 native amphibian species are threatened with extinction. chytridiomycosis is a fungal disease first identified in 1998 as a cause of massive amphibian deaths. in some severely impacted populations, a few individuals have survived, perhaps because of some natural resistance. if these resistant individuals continue to survive and prosper, new resistant populations might emerge. this would be an example of the founder effect artificial selection genetic drift natural selection sexual selection
